THE BOSTON AREA PHYSICS CALENDAR
Week of May 12-May 18, 1996

The Boston Area Physics Calendar is published weekly during 
the academic year by the Department of Physics and Astronomy 
at Tufts University.  You may send your announcements by 
e-mail (bapc@tuhepa.phy.tufts.edu) or FAX:(617-627-3878).  
We cannot accept announcements by telephone.  Entries should 
reach us no later than 11:00am on the Monday preceding the week 
of the event. ENTRIES RECEIVED AFTER THE DEADLINE WILL NOT 
BE PUBLISHED.

``Stellar Collisions and the Formation of Blue Stragglers'' 
DR. FREDERIC RASIO 
Massachusetts Institute of Technology 
 
 Abstract: 
 
It is now generally accepted that blue stragglers are formed by the merger
of two lower-mass main-sequence stars, either through direct physical collision
or in a close binary system. Clear evidence for binary mergers has been found
in the form of contact binaries among blue stragglers in low-density globular
clusters such as NGC 5466 and M71, as well as in many open clusters. Evidence
for direct stellar collisions comes from recent detections by HST of large
numbers of blue stragglers concentrated in the cores of very dense clusters
such as M15 and M30. In this talk the latest observations will be reviewed and
new results from supercomputer calculations of collisions and mergers between
two main-sequence stars will be presented. These new results have some
surprising implications that are changing our theoretical understanding of blue
straggler formation and evolution. The theoretical models and observational
data have now reached the point where direct comparisons are becoming possible. 
 
Tea will be served at 3:30 p.m.

``The Structure of the Proton''
ALBRECHT WAGNER
DESY and the University of Hamburg

Abstract:

Deep inelastic scattering experiments have always been the classical tool to probe
the innermost structure of matter.  The electron-proton collider HERA at DESY has 
provided a fresh look of unprecedented accuracy at the structure of the proton.  The
talk will focus on the measurement of the structure functions of the proton and
gluon and their interpretation in the framework of QCD, the theory of strong 
interactions.  The status of the measurements of the origin of the nucleon spin will
be briefly described.

Refreshments will be served at 3:45 p.m. in room 26-110
